CABBURETER FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed January 3, 1911. Serial No. 600,481.

To all whom it may concern: 7

Be it known that I, BARRY MAGNUTT, a citizen of the United States,residing at South Bethlehem, in the county of Lehigh and State ofPennsylvania, have invented certain. new anduseful Improvements inGarbureters for Internal-Combustion Engines; and I do hereby declare thefollowing to be a full, clear, and exact descrip tion of the invention,such as will enable others skilled in the art to which itappertains tomake and use the. same.

- My invention relates to carbureters for internal combustion engines.

This carbureter is designed to use the lower grades of fuel, such aspetroleum and crude oil.

My aim is to effect the vaporization of the fuel in an improved and moreefficient manner whereby the capacity of the carburetor is greatlyincreased and a superior quality of vapor is produced.

The invention consists generically of a series of electrically heatedgrids arranged transversely in the carbureter between the fuel inlet andvapor outlet.

The invention also consists in the features or construction andcombinations of parts hereinafter described, illustrated in theaccompanying drawing and specified in the claims.

In the accompanying drawing: Figure 1 is a central vertical sectionalview of a carbureter constructed in accordance with my invention. Fig. 2is a horizontal section taken on the line m-w of Fig. 1, and Fig. 3 is asimilar section taken on the line y-y.

Referring more particularly to the drawing, 1 designatesthe casinghavingthe air intake pipe 2 and the pipe 3, leading from the casing,entering near the bottom thereof. The fuel supply pipe 4 enters the topof the casing and delivers into a chamber 5 formed between the top ofthe casing and a horizontal partition 6. Said partition is provided withopenings or nozzles 7 distributed over its entire surface whereby thefuel is delivered in the form of a shower into the main portion of thecasing.

Intermediate of the partition 6 and the plane of the pipes 2 and 8,there are an ranged in the casing a plurality of horizontal grids 8',preferably spaced equi-distant apart. Each grid consists of a ring 9 ofinsulating material and a flat coil of wire extending across said ring,the bends the casing between the of the coil being seated in said ring.Said ring conforms to the interior of the casing and is secured inposition in any suitable manner, such as by the screws 10. The crosspieces of each grid, namely, the parallel portions of its wire coilextend transversely to those of the adjacent grid or grids.

The several grids may be connected in series, parallel, or in any othermanner. have shown them connected in series. The terminals of said gridsare connected to a suitable electric generator. While I have shown onlythree grids, it will be understood that a greater or less number of themmay be employed to suit conditions.-

In operation, the shower of fuel from the nozzles in the partition 6comes in contact with the several grids, in order, percolating throughfirst one and then another until, when it passes through the last andlowest grid, it has become completely vaporized and is in condition toform the proper admixture with the air for delivery to the.

cylinder of the engine.

Changes may be made in the details of construction of the devices hereinshown and described without departing from the spirit or sacrificing theadvantages of my invention. I, therefore, reserve the right to make suchalterations and adaptations as may fairly fall within the scope of myinvention. For instance, the grids may be formed in numerous other waysand of other materials than a continuous coiled wire.

I claim:

1. A carbureter, of the character described, having a liquid fuel-supplyport, an air intake port, and a vapor outlet port, an electric conductorin the form of a grid arranged transversely of the carbureter betweensaid fuel-supply and vapor outlet ports, and an electric generatorconnected to said conductor for heating the grid, said air intake portbeing arranged on the same side of the grid as the vapor discharge portwhereby the liquid fuel is obliged to pass through said grid before itis mixed with the air and passes out of the carbureter.

2. A carbureter, of the character described, comprising a casing havinga liquid fuel-supply port, an air intake and a vapor outlet port, a gridextendin entirely across fuel-supply and vapor outletports, said gridcomprising a frame of insulating material, suitably secured to the innersurface .913 the casing, and

scribed, comprising a casing having a liquid fuel-supply port, an airintake and a vapon outlet port, a grid extending entirely across thecasing between the fuehsupply and vapor outlet ports, said grid beingdetachable bodily from the casing and comprising a frame/of insulatingmaterial, and a" bent electric conductor extending across said framewith its bends embedded there1n,'and

an electric generator connected to said conductor for the purposespecified.

- In testimony whereof, I afiix my signatur, in presence of twowitnesses.
